Abstract (en)
[origin: EP3214628A2] A line-frequency rotary transformer is provided, including a primary core and a secondary core. The primary core is magnetically couplable to the secondary core. The primary core includes a first plurality of E-core steel laminates arranged in a first ring couplable to a stator. The primary core includes a primary winding disposed within the first ring and configured to transmit line-frequency AC power. The secondary core includes a second plurality of E-core steel laminates arranged in a second ring couplable to a gantry. The gantry is rotatably couplable to the stator. The secondary core includes a secondary winding disposed within the second ring and is configured to receive a line-frequency AC power induced in the secondary winding through the primary core and the secondary core by the primary winding.
